@looxonline Can you help me with the scheme? My controller has problems over the USB line. Strong heating of the stabilizer in the sot23 housing near the USB port. I really need a diagram and the name of the elements.
Thank you in advance and I hope for your help

Thanks a lot for the laid out scheme! She helped a lot. Can I also ask you to post TOP&BOT? The locations of the elements on the board are needed

@bigtreetech Tell me, what does this symbol on the diagram mean?

[bigtreetech]

Differential pair with impedance matching.

I've dealt with the problem on the board a bit. Due to a short circuit, the USB FE1.1S controller burned out, as well as the U6 - LPW5209AB5F-21 key.
The main problem is not high-quality pins for connecting the switching board. They break off and cause a short circuit
